This invention relates to davenportconstruction.

An object of the invention is the provision of; a hinge construction fordavenports which allows a davenport to become a bed-davenportwithaminimum of effort as to actuating the hinge onthepart of the operator.

Another object is the provision of a hingeconstruction for bed-typedavenports; which is simple of structure, inexpensive in cost: ofmanufacture, of few parts, and fool-proofin: its construe tionandoperation.

With the above-mentioned and. other objects in view, the inventionconsists in the novel and useful provision, formation, construction,association, and relative arrangement of parts, members and features,all as shown in certain em,- bodiments in the accompanying drawings,described generally, and more particularly pointed out in the claims.

In the drawings:

Figure 'Tis a perspective view of one hinge member,

Figure 8 is a perspective view of a second hinge member adapted tocooperate with the hinge member of Figure 7, and

Figure 9 is a perspective view of a bracket which may be used in thepractice of the invention.

Referring now to the drawingsl have shown a portion of a davenport,indicated generally as l, which has a back 2, seat 3, and framing 4adapted tobe supported by the usual legs; The back and seat, by way ofexample, may both include a rectangular framing carrying the usual coilsprings over which is placed padding, followed by upholstering material.Thus, when the back and seat are moved from the position of Figure '1 tothat of Figure 6, a bed structure resultsgin which the back and seat arein substantial alignment horizontally. The frame 4 includes what isordinarily known as a hinge board 5. This hinge board is adapted tocarry the elements of the invention, to be described, andsaid board isconnected to and becomes a partof the framing 4-. The hinge for thedavenportback and seat includes two members 6 and l. A hinge is used ateach end of the davenport. Member 6 is best illustrated in Figure 7, andincludes a part 8 which is flanged at 9, the part 9' being substantiallyatright angles to the plane of the part 8, with part 8 formed with anoilset and parallel portion Hi. It will be observed that flange 9 is atan angle other than degrees to the edge portions H and I2 of thepart 8.This construction is adhered to due to the method by which said hingepart is attached t0 the back 2, as shown in Figure 1. In other words,flange 9 is secured to the back, the part 8 extends downwardly andconnects with the other hinge part I, thus allowing the, back to have aslight tilt rearwardly relative to the seat. The offset edge l3mterconnecting parts 8 and it) provides a cam surface at I i,

a notch at l5 at the terminus ofone end of the cam surface, and a camnose It at the opposite terminus of the cam surface where it joins withthe edge 12. The other member I of the hinge is shown in Figure 8 andit, like member '6, provides a body portion H having a flanged end issubstantially at right angles to the plane of portion H and at an acuteangle to edges wand .26. The opposite end of part I1 is formed toprovide a cam edge at 2|, the cam edge being joined with a lip 22 at oneterminus thereof, while the opposite end portion merges with a camrecess 23. A nose portion 26 is formed by an extension of edge I9 whereit joins with the recessed portion That portion of part I! whichincludes the cam edge, lip, recess and nose will be designated as anentirety as 25, and the portion 25 is Pro.- vided with a cam slot 26.Cam slot '26 has a curved edge 21 merging with curved ends 28 and -29,the curved ends being joined by a concave edge 30. It is intended thata-bolt or pin should be passed through bore 3! of part II), and throughcam slot 26 for holding the parts in assemblage. This same bolt, whichis illustrated in Figure 3 at 32, likewise holds certain other elements,to be hereinafter described.

The flanges 9 and 18 are transversely bored at 33 and. 35, respectively,so thatscrews or other means may be passed through said bores forholding the flanges to the back and seat as, for instance, illustratedin Figure 6 at 35- and 36, respectively.

In Figure 9, I have provided a bracket 3- 1. This bracket includes twoparts 38 and 39 substantially in right angular relationship. Both parts38 and 39 are provided with transverse bores, as shown at 4B and 4 Iwhereby screws may be passed through said bores into the hinge board forsecuring the bracket in position of service. It is understood duringthis description that I am describing but a single end of the davenport,and the means used at said end for hinging the back and seat together,and that the opposite end would be identical as to construction andparts. A pair of links 42 and 43 are spacedly secured to the bracket 31by means of pin connections, as

illustrated in Figure 3 at 44 and 44 The opposite end of link 42 ispinned at 35 to member 6, while the opposite end of link 43 is securedby the pin or bolt 32 which joins members 6 and l together. e V

The link '43 is perforated at 46 and the hinge board carries a smallbracket 41, between which :bracket and perforation is a coil spring 48.

The operation, uses and advantages of the in- Vention just described areas follows;

If we assume that two. pairs of hinges, together with the associatedlinks 42 and 43, and brackets 31, have been secured at ends oi thedavenport between the back, seat, and hinge board, then the seatv may bemoved relative to the back so that the back may assume an angle tovpermit access within a compartment located beneath the seat, or topermitthe back and seat to assume the horizontal position shown in Figure 6,When the parts are in the position illustrated in Figure 1, the backbeing at an angle to the seat, link 43 engages a stop. pin 49 carriedbybracket 37. This lirnits movement of; the link in one direction andaids in preventing the back from dropping from the position shown inFigure 1. Also, the lip 22 of member I engages the notch l5 of member 6to prevent movement'between members 6 and I. In other words, members 6and 1 do not bove on the pin or bolt 32.

When it is desired to lower the back to form a bed, the seat 3 is raisedfrom the position of Figure 1 to that of Figure 2, the bracket!indicating a raised seat position. The pin 32 remains in the end 29 ofthe cam slot, with the result that the lip 22 engages the notch l5 andholds the seat in its raised position. At the. same timethe back islowered to a horizontal position, This permits accessby the operator to.any bedding contained in the compartment (not shown), and usuallyprovided beneath the seat. In the raising of the seat from the positionoi Figure 1 to. that of Figure 2, the movement is outwardly and upwardlyand the load is carried by the links 42 and 43. The link 4:3 is urgedforwardly by spring 48, with the result that slight physical effort isexerted to raise the seat to. the position of Figure 2. Having removedbedding from the compartment provided therefor, the seat is tiltedfurther or from the position of, say, Figure 2, to that of Figure 4.This tipping movement brings the breaking cam into action, this breakingcam including the nose l6 and the recess 23. The nose I6 is receivedwithin the recess 23 and moves the pin 32 from the position of Figure 2first into the concave edge 30, as shown in Figure 4, and then intoportion 28 of the slotted cam, as shown in Figure 5. The two cam faces14 and 2| are separated, as shown in this figure. The seat may then belowered to a horizontal position as shown in Figure 6. When 4 this seatis so lowered, the pin 32 is shifted so that now it engages the portion30 of the cam slo If it is desired to restore the davenport totheposition of Figure 1, the seat is lifted, which will cause the pin 32to'be received within the end 28 of the cam slot, whereupon the notch l5and lip 22 will co-engage, as indicated in Figure 2, andthe lowering ofthe seat will raise the back to the position shown in Figure 1, Duringthe move-- ments just described, the cam edges l4 and 2| co-engage, tothe end that the pin 32 travels to proper position. against the end 29within the cam slot.

It will be seen that the present invention pro-- vides a shifting pinbetween the two hinge members, the pin being controlled as to itsposition by a cam slot and which pin is caused to move within the camslot by the co-engaging cam edges of the two hinge members, to the endthat the twohinge members may assume a locked-againstmovement position,which look may be broken upon moving one of the hinge members, whereuponthe cam edges may co-engage so that the hinge members may assume arelative angularity. I have provided, by this invention, a simple meansfor controlling the position of the back and seat members of a davenportwithout the necessity of providing spring-pressed pawls, or the like,operating in conjunction with a toothed rack, as is ordinarily employed.The construction shown is positive in its operation, will at all timesoperate in the same way, with nothing to get out of order other thanthat caused by wear of the parts.
